Hello, I am working on a multiple-Arduino project, using a two-wire RS485 network. One Arduino will function as the master; the rest (as many as 10) as slaves. I have the hardware side of it set up with no issues, and I have a very primitive protocol in place to send data to the slaves. Ultimately,…

Look for an RS485 tutorial
